   Hi @KurtYoung , I renamed the node name to `LookupJoin` and move the 
snapshot on proctime verifying to rules in the second commit: `rename to 
LookupJoin`.

   Hi @godfreyhe , I add the `JoinPushExpressionsRule.INSTANCE` rule into 
predicate pushdown stage to make sure the calculation expression can be pushed 
down (to make sure `ON a+1 = b` is an equi join).  That's why several results 
of plan test are changed. I have checked, the changes are reasonable.
   
   It would be nice if you can have a look too.
